The redshirt-junior quarterback will begin classes in May and have the opportunity to play immediately due to being a grad student.
Trickett, the son of offensive line coach Rick Trickett, was one of four quarterbacks battling for the starting job in Tallahassee this spring.
Although Trickett entered spring camp labeled the starter by head coach Jimbo Fisher, his decision to transfer speaks volumes of the job that redshirt freshman Jameis Winston has done.
Trickett took to twitter on Wednesday to announce his decision.
"It's official, I will finish my academic/athletic career at WVU," Trickett tweeted. "This is a dream come true to be playing for the state I love."
Trickett appeared in 16 games in his time at FSU, but started only two. Although the Seminoles lost both games, Trickett did set a career-high 336 passing yards in a five-point loss at Clemson.
West Virginia was one of three schools that Trickett took into consideration. He also took visits to Auburn and South Florida before making his decision. But, in the end, the opportunity to go back home was what won him over.
Trickett lived in West Virginia for seven years when his father was the offensive line coach for the Mountaineers and still has family in the state.
